JOURNAL-BOX FOR ROTARY PUMPS.'

SPI!(`JI1ICATIO1\I forming part of Letters Patent No. 357,797, dated February 15,1887.

Application filed January 11, 1886. Serial No. 188.155. No model.)

.To @ZZ whom it may concern:

Beit known that I, BENJAMIN F. TEER, of the city of Buffalo, in the county of Erie and State of New York, have invented new and useful Improved Journal-Boxes for Rotary Pumps, of which the following is a speciiication.

This invention relates to an improvement in that class of rotary pumps which are provided with a revolving piston-cylinder arranged eccentrically` in an inclosing shell or case, the

cylinder being provided with journals which revolve in suitable boxes formed on or secured to the sides of the shell or case. A pumpbf this character is described and shown in Letters Patent of the United States No. 344,063, granted to me June 22, 1886, to which reference is here made.

The object ot' my present invention is to improve the construction of the boxes in which the journals of the cylinder revolve,(whereby these journals are kept sufficiently lubricated and prevented from ruiming dry.

The invention consists, to that end, of the improvements which will be hereinafter fully l set forth, and pointed out in the claims.

In" the accompanying drawings, Figure l is a longitudinal sectional elevation of a Ypump provided with my improvements. Fig. 2 is a cross-section in line :v x, Fig. 1, on an enlarged scale. Fig. 3 is a crossesection in line y t/,Fig l, on an enlarged scale.

Like letters of reference refer to like parts in the several figures.

- A represents the inclosing shell or case of the pump, which is supported on a suitable baseframe and provided with a suction-nozzle, b, and a dischargenozzle, c, in the usual manner.

D represents the pistoncylinder, and E the pistons sliding in 'ways formed therein.

g represents the driving-shaft formed on one end of the cylinder D; and his the stuffing-box formed in the adjacent head, H, of the shell A, and inclosing thc shaft g.

H is the gland of the stuffing-box, secured thereto in any suitable manner and provided in its outer end with a screw-threaded collar, t, which receives an internally-threaded stufiing-nut, I. A. suitable packing, t', is interposed between the nut I and the collar t', to retain on the journal the oil, which is introduced through an aperture, It', from the oilcup J.

j is a longitudinal groove formed on the inner surface of the gland H', and extending nearly the length thereof and communicating with the aperture h. rlhe groove j forms a passage for the oil from the aperture h lengthwise of the shaft g, wherebythe portion of the shaft which revolves in the gland H is kept sufficiently lubricated.

K represents a journal formed on the opposite end of the cylinder D. y

Z is a stuffing-box formed on the adjacent head L of the shell A and embracing the j onrnal K.

M represents the gland of the stufng-box Z, constructed with a closed outer end, m, which covers the outer end of the journal K, whereby the escape of the oil from the gland is prevented. The gland M is provided with an oil-aperture, O, which communicates with channels S, extending downwardly and partly around the journal K, and which have sufficient capacity to hold a suitable quantity of oil. The gland M is also provided with a longitudinal groove, r, which communicates with the aperture O and channels S. The groove r is formed on the inner surface of the gland, and extends to nearly the inner end of the gland.

l is an oilcup secured to the gland M and communicating with the aperture O, whereby i the oil is supplied to the channels S and groove r. As the journal K is the only support of,

the cylinder D at the end on which it is formed, it requires this extra protection against running dry, while the shaft g, which is supported in lseveral bearings, is more easily kept prop- `erly lubricated. The gland H is also provided with channels similar to the channels S, which communicate with the oil-aperture it and extend downwardly and partly around the shaft g, to insure a more complete lubrication to the shaft g. A suitable packing, u, is interposed between the stnfng-boxes and the journals and the inner ends of the glands, whereby the oil is retained on the journals.

I claim as my invention-.-

l. The combination, with an inclosing-shell, A,and a piston-cylinder havinga journal, K,

IOC

of the stufng-box Z and the gland M, having its outer end closed, whereby the outer end of the journal is covered, substantially as set forth.

2. The combination, with an inolosing-shell, A, and a piston-cylinder having a journal, K, of the stufling-box Z and a gland, M, having its outer end closed and provided with oilohannels S, extending downwardly and partly around the journal, substantially as set forth.

3. The combination, with aninolosing-shell, A, and a piston-cylinder having journal K, of the stuiling-box Z and a gland, M, having its outer end closed and provided with an aperture, O, channels S, and groove r, substantially as set forth. Y

4L. The combination, with aninolosing-shell, A, and a piston-cylinder having a drivingshaft, g, of the stufngbox h, the gland H, provided with a threaded. collar, z', and the stuffing-nut I, applied to said collar, substantially as set forth.

Witness my hand this 30th day of December, 1885.
